How can I "select all" and delete a group of emails at the same time? This is from a non gmail accout set up on my dell streak 5.

Also, do i need to purchase app that will clear the trash bin in the email account? i have over 325 deleted emails in the Trash folder and have to click one by one the delete. seems there should be a way to "select all"

Purchase Enhance Email from the Android Market. This is a souped up version of the standard email tool that comes with theStreak.

Enhance Email lets you do a batch delete, move email among folders and get rid of the 100s of old email sitting in the trash folder with one step instead of selecting one by one, then deleting over and over.
